I hope you are all doing well. I am doing OK. The other day I went horseback riding with an organization for people with physical and developmental disabilities. I didn't think I would be able to ride the horse, I was sure my core would not be strong enough to hold me up. When I go there, there was no ramp either so I had no way on getting on to the horse. Well... When most people were done riding, a couple of people came and said they would help me out. One guy lifted me onto the horse (yeah, I feel sorry for him), and I was very happy to find out that my core is strong enough to hold me up on a horse. I tried horseback riding about a year and a half ago, and a combination of fear, but also lack of strength/coordination of my core muscles made me get off right away.
Horseback riding is supposed to be really good for us, and I can only recommend that you look into similar problems around your home.
